Detailed Description

template<class OBJECT>
class bslma::ExceptionGuard< OBJECT >

This class provide a mechanism to verify the strong exception guarantee in exception-throwing code. On construction, this class stores the a copy of an object of the parameterized type OBJECT and the address of that object. On destruction, if release was not invoked, it will verify the value of the object is the same as the value of the copy create on construction. This class requires the copy constructor and operator == to be tested before use.

Constructor & Destructor Documentation

ExceptionGuard() [1/2]

template<class OBJECT >

bslma::ExceptionGuard< OBJECT >::ExceptionGuard ( const OBJECT *  object, int  line, Allocator *  basicAllocator = 0  )

inline

Create the exception guard for the specified object at the specified line number. Optionally, specify basicAllocator used to supply memory.

ExceptionGuard() [2/2]

template<class OBJECT >

template<class ALLOCATOR >

bslma::ExceptionGuard< OBJECT >::ExceptionGuard ( const OBJECT *  object, int  line, const ALLOCATOR &  basicAllocator  )

inline

Create the exception guard for the specified object at the specified line number. Optionally, specify basicAllocator used to supply memory.

~ExceptionGuard()

template<class OBJECT >

bslma::ExceptionGuard< OBJECT >::~ExceptionGuard

(

)

Destroy the exception guard. If the guard was not released, verify that the state of the object supplied at construction has not change.

Member Function Documentation

release()

template<class OBJECT >

void bslma::ExceptionGuard< OBJECT >::release ( )

inline

resetValue()

template<class OBJECT >

void bslma::ExceptionGuard< OBJECT >::resetValue ( const OBJECT &  value, int  line  )

inline

Reset the expected state of the guarded object, if an exception should propagate past this guard, to the specified value, which is set from the specified line.
